misc: pci_endpoint_test: Avoid using hard-coded BAR sizes
BAR sizes are hard-coded in pci_endpoint_test driver corresponding to the sizes used in pci-epf-test function driver. This might break if the sizes in pci-epf-test function driver are modified (and the corresponding change is not done in pci_endpoint_test PCI driver). To avoid hard coding BAR sizes, use pci_resource_len() API. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
